Definitions

  • the invention relates to a fastening system for elongate, transversely rigid connecting elements, in particular rod-like connecting elements, according to the preamble of claim 1.
  • An attachment system of the aforementioned type is known from DE 44 45 233 C1 known in which an elongate, transversely rigid connecting element, a piston-cylinder unit is provided in the form of a gas spring, the piston and cylinder side at their opposite ends in the transverse direction open eyelets for receiving connection bodies associated fastening bolts.
  • the fastening bolts are guided and held in the eyelets via sockets, which can be inserted into the eyelets and which are axially fixed by latching by means of axial stop collars to the receiving eyelet, wherein the fastening bolt is provided in the region of its free end with a locking groove into which a frontal Locking collar of the socket engages.
  • the bushings can also be injected into the eyelets.
  • fastening bolts are designed as ball pins, which engage in eyelets of transversely rigid connecting elements and in. These are fixed via plug-in sockets, which are held on the shape of their contour axially and rotatably in the eyelets and in turn dome-shaped formations for have the ball studs.
  • the ball pins are not tied to an alignment of the bolt axis to bushing axis for insertion into the sockets, so it is also possible to mount in such a fastening system transversely rigid connecting elements between connecting bodies, which are offset in the direction of the bolt axes to each other and starting of which the bolts extend against each other, so that there is a setting of the bolt axes to the axes of the respective receiving lugs in the assembly starting position for mounting.
  • the invention has the object of providing a fastening system of the type mentioned in such a way that even a cylindrical fastening bolt regardless of a possibly entangled position of the pin axis to the eye axis with a simple structure and cheap mounting options in an eyelet is to be used.
  • the axial stop collars are assigned on the one hand the fastening bolt or the fixing pin fixed position connecting body and on the other hand, to be inserted into the eyelet bush, so that the eyelet is located on the bolt latched bush between these stop collars of which the socket-side stop collar lies axially in the transition to the socket-side latching collar, which in turn is axially spaced from the stop collar.
  • the socket is inserted from both sides into the eyelet and opposite to each opposite to the insertion of the Socket extending bolt axially locked, in particular latched or braced and locked.
  • the locking collar is formed by the socket-side stop collar outgoing, conically tapering radially on their free end, resilient locking fingers, which is assigned a corresponding locking groove on the part of the fastening bolt, as so on the locking fingers a tolerance compensating axial, possibly also adjustable with respect to the amount of clamping force clamping the eye between the sleeve associated stop collar and the bolt-side stop collar can be achieved, this stop collar can of course also be provided on the bolt-carrying connector body.
  • shims can be provided between the stop collars and the eye over which both friction conditions improve as well as axial tolerances can be compensated.
  • the fastening system of the invention allows the use of the through the sockets in their in The eyelets mounted state occupied space to balance the axial offset or the restriction due to deviations in the mounting starting position and it can be done centering the eyelets to the bolt on the jacks humorsteckenden when the connecting element has reached the mounting end position corresponding to the mounting end position.
  • Fig. 1 shows a schematic perspective view of an elongated, transversely rigid connecting element 1, which is shown as a rod, but which can also be formed as a variable-length connecting element by a telescopic cylinder, a gas spring or the like.
  • the connecting element 1 is provided at its opposite ends with open in the transverse direction eyelets 2, 3 and to connect via these eyelets 2, 3 with fastening bolts 4, 5, which are each associated with a connector body 6, 7, wherein as connecting body 6, 7 linkage elements, Frame parts or the like come into question, as given for example in conjunction with rear doors, trunk lids, hoods or the like in vehicles.
  • the fastening bolts 4, 5 are to be fixed in the respective eyelets 2, 3 via bushings 8, 9, which are to be inserted in the mounting end position into the eyelets 2, 3 and support these against the fastening bolts 4, 5.
  • the insertion directions for the sockets 8, 9 are indicated by the arrows 10 and 11.
  • Fig. 2 shows a schematic plan view of the starting position shown in Fig. 1 when threading the rod-shaped connecting element 1 on the connecting bodies 6 and 7 associated bolts 4, 5, wherein in this initial position bar-shaped connecting element 1 is at an oblique angle to the axes of the bolts 4, 5, which are parallel to each other, so that for threading the end provided for the connecting element 1 eyelets 2, 3 on the fastening bolts 4, 5, the illustrated entangled position in which the connecting element with 1 'is necessary.
  • the Schränkungswinkel corresponding to the starting position between the axis of the respective bolt 4, 5 and the axis of the respective eyeletberichtfädelnden 2, 3 is referred to the assembly starting position in Fig. 2 with 12 and 13 respectively.
  • the connecting element 1 assumes its extension corresponding to the assembled position - the connecting element 1 extends perpendicularly to the bolts 4, 5 - the respective bushing 8 or 9, the bolts 4, 5 can be inserted into the respective eyelet 2, 3 and occupies the space that was necessary for the entangled insertion of the respective bolt 4, 5 in the corresponding eyelet 2, 3.
  • the axial fixation of the respective eyelet, 2, 3 with respect to the accommodated pin 4, 5 is achieved at the same time via the bushing 8, 9.
  • Fig. 3 shows the structural design based on a connector body 7 and a fixed to the connector body 7 mounting bolts 5, which may be connected in any manner with the connector body 7, wherein in the illustration of FIG. 3, then a stop collar 14 provided on the connector body 7 is, which is associated with the bolt 5, but also by an annular projection, the connecting body 7 or a washer can be formed.
  • the bolt 5 projecting toward the connection body 7 has a latching groove 15, which is delimited towards the free end of the bolt 5 via a cap-like end piece 16 of the bolt 5.
  • the connecting element 1 is to guide over his eyelet 3 and is supported.
  • the inner diameter 18 of the eyelet is larger than the diameter of the support member 17 of the mounting bolt 5, and given in the final assembly annular space between the support member 17 and the inner diameter 18 of the eyelet 3 is filled by the sleeve body 20 of the bushing 9, at its relative to the plug according to arrow 11 rear end carries the radially outwardly cantilever stop collar 21.
  • locking fingers 22 Starting from the stop collar 21 extending counter to the insertion according to arrow 11 locking fingers 22 which taper towards their free end to each other so that they engage in the threading on the fastening bolt 5 state of the socket 9 in the locking groove 15 and thereby the axial position of the socket 9 and also secure the eyelet 3 of the connecting element 1.
  • FIG. 3 further shows that a washer 23 is provided between the eyelet 3 and the stop collar adjacent to the connecting body 7, be it with regard to an improvement in the friction conditions between the stop collar 14 and the eyelet 3, be it for adjusting axial tolerances.
  • a washer 23 is provided between the eyelet 3 and the stop collar adjacent to the connecting body 7, be it with regard to an improvement in the friction conditions between the stop collar 14 and the eyelet 3, be it for adjusting axial tolerances.
  • latching collar 24 forming latching fingers 22 can also be an axial tension of the eyelet 3 reach the connection body 7, so that with the inventive solution also an axially play-free mounting of the connecting element 1 to the respective connection body 7 is reached.
